Answer:

9. First Five terms

If n=0. Then,

$\frac{4(0) - 5}{2}$

$\frac{0 - 5}{2} = \frac{ - 5}{2}$

If n=1. Then,

$\frac{4(1) - 5}{2}$

$\frac{4 - 5}{2} = \frac{ - 1}{2}$

If n=2. Then,

$\frac{4(2) - 5}{2}$

$\frac{8 - 5}{2} = \frac{3}{2}$

If n=3. Then,

$\frac{4(3) - 5}{2}$

$\frac{12 - 5}{2} = \frac{7}{2}$

If n=4. Then,

$\frac{4(4) - 5}{2}$

$\frac{16 - 5}{2} = \frac{11}{2}$

If n=5. Then,

$\frac{4(5) - 5}{2}$

$\frac{20 - 5}{2} = \frac{15}{2}$

If n=6. Then,

$\frac{4(6) - 5}{2}$

$\frac{24 - 5}{2} = \frac{19}{2}$

On a piece of paper, graph y≥ x - 1. Then determine which answer choice

zhannawk [14.2K]

Based on the given inequality of y≥ x - 1, the graph that matches it best is C. Graph A.

<h3>How are inequalities graphed?</h3>

When graphing an inequality with the "greater or equal" and "less or equal" signs, the line will be a steady line as shown by graphs A and B.

If y is the larger or equal variable, the shaded area will be to the left of the line.

The inequality is y≥ x - 1 which means that the line should be steady and the shading should be on the left of the line. Graph A is therefore the correct graph.

What are the ordered pairs of the

9966 [12]

Start by writing the system down, I will use $y$ to represent $f(x)$

$y=x^2-5x+3\wedge y=-3$

Substitute the fact that $y=-3$ into the first equation to get,

$-3=x^2-5x+3$

Simplify into a quadratic form ( $ax^2+bx+c=0$ ),

$x^2-5x+6=0$

Now you can use Vieta's rule which states that any quadratic equation can be written in the following form,

$x^2+x(m+n)+mn=0$

which then must factor into

$(x+m)(x+n)=0$

And the solutions will be $m,n$ .

Clearly for small coefficients like ours $5,6$ , this is very easy to figure out. To get 5 and 6 we simply say that $m=3, n=2$ .

This fits the definition as $5=3+2$ and $6=2\cdot3$ .

So as mentioned, solutions will equal to $m=3, n=2$ but these are just x-values in the solution pairs of a form $(x,y)$ .

To get y-values we must substitute 3 for x in the original equation and then also 2 for x in the original equation. Luckily we already know that substituting either of the two numbers yields a zero.

So the solution pairs are $(2,0)$ and $(3,0)$ .

Hope this helps :)
